Well, assuming I'm right about the stack overflow, I don't think it's
an error path, as increasing the block size fixes it. Are you really
sure we are generating the deffereds right? It looks to me like the
stack overflows when the chain gets too long, indicating that we're
doing something subtly wrong when we "schedule" the next read, causing
the eventual overflow.
But I'm a n00b at deferreds, so disregard if I'm an idiot. If I was
more sure I'd be posting a patch. :-)
